Was bedeutet das?

Viele Grüße

also entweder der router hat sich aufgehangen und weiß nicht mehr was er tut oder jemand belastet ihn von außen was auch zu ersterem führen kann. schon durch recht harmlose portscans kann ein router überlastet werden. nen richtiger ddos sollte noch heftiger aussehen. nen neustart sollte schon helfen.

also wenn ich einfach eine der meldungen in google nachschlage klingt das wirklich nach ddos oder so. passiert...

 

[Naddel_81]

danke! habe nun einen "reboot scheduler" im router eingerichtet, der ihn nachts täglich um 3:50 Uhr neustartet. das sollte ihn frisch halten

 

[evilnear]

naja, eigentlich brauchst du ja nur ne neue ip adresse vom provider. nen täglicher reboot klingt da nach ner ziemlich heftigen lösung aber helfen sollte es in dem fall.

 

[Naddel_81]

IP ist die alte geblieben (WAN restored) dank Kabel. Aber Sys-Log sieht wieder sauber aus.

 

[evilnear]

bei nem richtigen ddos hilft das dann aber nicht viel da der bei gleicher ip einfach weiter geht als wäre nichts. kann natürlich sein das ein frisch gestarteter router damit besser umgehen kann.

 

[Naddel_81]

war vermutlich auch kein DDoS, sondern die "ausgereifte" asus wrt software im router. hab das OS neu gestartet und lasse ihn nun einmal täglich (nachts) refreshen. der hardware wirds hoffentlich nicht schaden, oder?

 

[chrigu]

nein. und wenn doch, ist das kein grosser verlust

 

[Naddel_81]

du meinst, weil die asus router sowieso elektroschrott sind?

 

[chrigu]

nein, sicher nicht. falls der kaputtgeht, kostet ersatz ja nicht die welt

 

[Naddel_81]

aber etwas wahres ist schon dran: die asus software ist mist. habe mich gerade gewundert, wieso der "reboot scheduler" nicht funzt. ein bug in der FW! also hab ich mir ein .vbs auf den server gehauen, was nachts um 3 uhr per telnet den router zum neustart zwingt.
traurig, dass die hersteller ihre betriebssysteme nicht mal testen.
